The side frame members 7 1 of the inner casing are each provided attheir base with a wooden cleat 82, extending along and above the framemember 79 and having a s slighl; downward. slant toward the rear for thepurpose of supporting a sieve, which iiulieal'ed in its entirely by thenumeral 8?).

"from the shaft 9) bya similar lever 97 in such manner that the interior casing 92 may beoscillated back and :liorth upon the pairs of lovers 93 and 97 in orderto shake the sieve 83 supported in the interior casing.

in order to provide for the actuation of the interior Easing member andthe sieve, the shalt 100 oi. the fan, further to be described, ma beprovided at one end with an ercei'itric 101, consisting; 0;": a pulleykeyed to the shaft 100, and having a crank 102 The c uni; 102 has aconnecting rod 103 pivotally r ounlied thereon, the said connecting rodextending to the bolt 98, where it pivot-- ally connected to theinterior casing 92 in such manner that rotation of the shaft 100reciprocates the connecting rod 103 and with it the interior casing 92and the sieve 8 :3.

in using, my sweet. clover thrasher upon a binder it has been found chatwhen the binder is on the side ofa hill the sieve 88 may have no slant,such as is required. to actuate the seed over its surface, or the sieve83 may on a side hill. have an excessive slant so that the grain willroll oil the end. Oili the sieve. in order to obviate this (.litliculty1 provide for u'ieans of adjustment. oil the slant; of the sieve withinconvenient reach of the drivefis hand, comprising the follown elements.The shalt $.19, which pi votally es pports the two links 97, which intheir l urn support the interior casing 92, is n unted upon the exteriorframe members 0 the operation of themachine as well as when i isstanding still.

.Tnorder to raise the shaft; 99 when desired, 1 provide a rod 105 whichmay extend across the full width of the thrasher, being pivoted in thetop of the side members 21 and 22,

and the rod may be provided at each end with crank member 100,pivot-ally connected with the shaft 99 as shown. At an inter: liatcpoint the rod 105 may be upbent to form an actu ting crank 107, to whichmay be pivotally connected a pull rod 108, having a plurality of notches109. in order to support the pull rod 108 in adjusted positi n, theupper frame member 412 of the exterior casing may be provided with a Usha ied stirrup 110, which is fixed (hereon by bolts any coi'ivenientmeans in such manner that the pull rod 108 may be hooked upon thestirrup 110 in any of a plurality of adjusted positions by means of thenotches 109. The end of the pull rod 108 is in convenient reach of thedriver and when desired or when the binder is operating on the side of ahill, the operator may pull the rod. 108 and hook in one of the notches109 upon the stirrup 110, thereby turning the crank 107 on the rod 105,actuating crank 106 and lifting the shaft 99 at both ends in the slots101. This raises the pivotal points of support of links 97, therebyalterthe height of th rear end of the interior casing 92, and henceregulating the slant of the sieve.

Supported upon the shaft 99, within the interior casing 92, is the rod111 of substantially U shape, the yoke 112 of the U extending across thewidth of the interior casing 92, and the ends of the U being fixedly supported upon the shaft 99. The U shaped member 111 supports upon its yoke112 a loosely pivoted sheet metal lid 113 formed of substantiallyrectangular sheet of metal of a length slightly than the width of theinterior casing 92, and having a pivot formed by a flange 11 1 bentabout the yoke 112. The lid 113 extenijls downwardly behind the strawrack 73 and serves to direct the straw upon the straw fingers 115,further to be described.

1 fxcdly si-ipported upon each of the walls 741- is a journal member 116provided. with a notch 1.17 for the purpose of pivotally supporting ashaft 118 which actuates the straw lingers 115. The shaft 118 hasextending from it in a rearward direction a plurality of thin metal rods115, as shown in Figure (l. somewhat after the manner of a pitch forkhaving: prongs of greater length and number. in the finished machine thestraw fingers are about two feet in length, but the length of theseelements may be varied depending upon the length of the sieve abovewhich they are situated.

The shaft is keyed to a pair of crank arms 119, one at each side, andthe upper ends of the crank arms 119 are each connected by n ink 120 tothe fixed shaft 112, which also oscillating interior casing 7 1, suchmovement results in lifting the straw lingers 115 up and down from theposition shown in Figure 2 to that shown in Figure 8 and back, corresponding to the oscillating motion ofthe interior casing. The strawlingers 115 are, the efore, adapted to receive the straw from the strawrack '73 and shake it up and down above the sieve to aid in removing theseed. therefrou'i. The straw rack, indicated in its entirety by thenumeral 73, consists of a pair of side Frame members 121 having an upperedge of approximately saw tooth shape, the length of the teethincreasing toward the rear end of the straw rack. The forward sides ofthe teeth, which are the sides having the least slant, are covered by aseries of pieces of sheet metal 122 of a length slightly less than thewidth of the interior casing 92, in such manner that the straw rackconsists of a series of successively olisct plane surfaces 122, havingholes between said surfaces as at 123 to permit the d ropping through ofthe seed, and the upper edges of the places 122 may serve as teeth:ulvancing the straw to the rear with each oscillation, but permittingthe straw to slide over the same when the interior structure 92oscillates to the forward position.

The straw rack 73 is pivotally supported at its forward and lower endupon the shaft 95, which is loosely pivoted in the opposite sides 7 1 ofthe interior casing 92, and the rear end of the straw rack 73 rests uponthe shaft- 118, which supports the straw tingers 115. In order to givethe straw rack 78 a slight upward movement, the portion of the shaft 118which supports the straw rack may be made square or otl'ierwise departfrom the cylindrical. shape, as shown at 125 resulting in a slightalteration of the height of the rear end of the straw rack duringoscillation of the interior casin 92.

ne fan 91 consists of an ex lar casing 126 formed upon circular portionsof the walls 21 and 22 of the harvester casing, and extending inward andupward at 127 to a point above the seed box 89. The ends of the fancasing 120 may be left open for the entrance of air, and the shaft 100may support a plurality of spiders 1.2r having a plurality of wooden ormetal cross members 129, which by their rotation serve to force acurrent of air out of the orifice 130. Thesha'it 100 is driven by awooden pulley 131 and by a belt extending from the pulley 52 upon theshaft 31 of the toothed cylinder 18. It will be observed that my fanruns at a much slower speed than the fans usually employed in tlirashersbeing attached to the same shaft that operates the oscillating sieve,because the use of a high speed fan such as is usually employed inthrashers would result in the blowing of the seed off the sieve 83.
